Design and Implementation of Face Recognition System Based on Raspberry Pie

A complete face recognition system needs to include at least image acquisition, face detection, face comparison, and verification. This paper proposes a face recognition system based on Raspberry Pie 3B + and Ali cloud platform. The image is collected by an external HD camera, and the Haar-like algorithm provided by OpenCV is used for face detection. The face comparison function is realized through the Ali cloud interface, and the data storage is completed through the database MySQL. To facilitate information management, a web application management system based on Java SpringBoot is implemented. Through testing, the system can basically achieve the expected function, and the confidence performance of the same face images is in line with expectations.
